Bethel (foot) missed the entire offseason program, the Cardinals' official site reports.
After inking a three-year extension in early December, Bethel was pressed into starting duty within weeks due to Tyrann Mathieu's torn ACL in Week 15. Bethel subsequently tallied 25 tackles, four passes defended, and one interception in four games, including two postseason tilts. As the offseason proceeded, the team allowed veteran cornerback Jerraud Powers to leave via free agency, which placed Bethel at the top of the depth chart at cornerback opposite Patrick Peterson. However, Bethel's offseason has so far centered about rehab from surgery to repair a "slight" fracture in his foot. With no activity in the offseason program, he may have hindered his chances in pursuit of the gig, but the prudent approach is expected to ensure that he's 100 percent once training camp begins in late July.
Mathieu's (knee) availability in Week 1 against the Patriots will be dependent upon his health, the Arizona Republic reports. "If I'm 90 percent, then I don't necessarily want to go out there," he said Sunday. "But if I'm 100 percent, I definitely want to be out there."
Embedded within his second rehab effort from a torn ACL -- the other occurred near the end of his rookie year in 2013 -- Mathieu's reticence to take the field isn't a shock, especially after logging just 13 games in a generally subpar 2014 season. With an unimpeded offseason under his belt last fall, he was the centerpiece of the Cardinals' defense, accumulating 89 tackles (80 solo), five interceptions (one for a touchdown), one sack, and one forced fumble in 14 contests. The season-ending injury resulted in a less imposing unit that was ultimately embarrassed in the NFC championship by the Panthers, which his representatives are likely pointing during the ongoing conversation about a contract extension. No matter if the sides come to an agreement, Arizona could be without its starting slot corner, if he deems himself unready.
Peterson (ankle) took part in individual drills during the Cardinals' mandatory minicamp last week, the team's official site reports.
Peterson hasn't missed a game in his five-year career, but nagging ankle concerns seemingly forced the All-Pro cornerback under the knife as a preventive measure in mid-April. Handed a 6-to-8 week recovery timetable, his lack of participation in OTAs wasn't a surprise by any means. His return to drills during minicamp signals that his rehab is on schedule, though, with the aim of full health by the time training camp rolls around in late July.
Kaepernick (shoulder) returned to practice for the first time this offseason, the San Francisco Chronicle reports.
Initial reports stated that Kaepernick would be limited to individual drills during the 49ers' three-day minicamp, but he ended up participating in the team's seven-on-seven sessions as well. He wasn't going at 100-percent, but he was seen firing the ball close to 50 yards down the field. Kaepernick was also noticeably slimmer, but that was to be expected after not being able to work out during his shoulder rehab. His health, weight and adaptation to Chip Kelly's offense will all be things to monitor this offseason to determine whether Kaepernick can bounce back in 2016.
Bethea (pectoral) is back at full strength and expected to start the season at strong safety, CSN Bay Area reports.
Bethea suffered a torn pectoral muscle and missed the final eight games of the season in 2015. He didn't have a spectacular campaign (44 tackles, zero interceptions), but he has the potential to put up solid IDP numbers playing on a Chip Kelly defense that is asked to be on the field for a high number of snaps.
Williams' contract with the 49ers has been reworked into a one-year deal worth up to $6 million due to the uncertainty surrounding his availability for the beginning of the upcoming season, CSN Bay Area reports.
Williams initially agreed to a reported five-year, $27.5 million contract with the 49ers following a career year last season, but after he couldn't pass a team physical due to multiple offseason ankle surgeries, Williams contract was reworked into a one-year deal. A player that's had numerous procedures to his left leg during his pro career, Williams' status for the start of the 2016 is in question following his latest operations, leaving the 49ers in need of some depth up front in case he's unavailable.
GM Trent Baalke claims Dorsey is making "very good progress" in his recovery from an ACL tear, Tim Kawakami of the San Jose Mercury News reports. Regarding Dorsey's availability for Week 1, Baalke went on to say, "I'm never going to give a definitive [answer] because I don't know. He could always have a setback coming up. But right now he's making progress, he looks good, his mind's in a great place, and ready to roll."
Despite this endorsement of health, Dorsey is almost certainly slated for the PUP list to start training camp. However, he won't necessarily begin the season there. Dorsey suffered the torn ACL last season against the Seahawks on Nov. 22, and although occurring late in the season, he could certainly be "ready to roll" come opening day. Comparatively, DT Geno Atkins suffered an ACL tear in Week 9 of the 2013 season, and was good to go for Week 1 of 2014.
