Multiple news outlets are reporting Michael Crabtree's stitches have been removed from the right ankle where he tore his Achilles. He's expected to begin rehab shortly to have a chance to play this season.
The San Francisco Chronicle reports Niners linebacker Aldon Smith isn't sure if he'll be cleared in time for the start of training camp after having surgery to fix a torn labrum in his shoulder earlier this offseason.
When asked about sitting out the 2013 season because of a knee injury suffered in college, 49ers rookie running back Marcus Lattimore told the San Francisco Chronicle "I think that would be fine." Coach Jim Harbaugh said the right knee "looks good structurally" but warned against a quick return. Lattimore suffered a dislocated right knee cap with three torn ligaments in a vicious play last October, ending his collegiate career after deciding to turn pro.
49ers running back Kendall Hunter participated in team drills this week according to the official team website. Hunter is working his way back from a torn Achilles. "Kendalls on track," was all coach Jim Harbaugh said. He's expected to be ready for training camp.
The Sacramento Bee reports that the 49ers could open training camp with Kyle Williams as the starter opposite Anquan Boldin with Michael Crabtree (Achilles) out. Williams, according to the report, is listed ahead of A.J. Jenkins for the "X" receiver with Boldin starting at the "Z."
Speaking on SiriusXM NFL Radio, Niners receiver Mario Manningham said he's feeling good and that his knee is getting stronger but has no timetable for his return. Manningham is hoping to be in the mix to help fill in for hurt Niners receiver Michael Crabtree but has to work his way back from a torn ACL first.
Defensive end Justin Smith has signed a two-year extension through the 2015 season with the 49ers, according to Comcast Sportsnet. Smith wouldn't speculate much on his future a week ago when meeting with the media but did say he will be ready for training camp after playing through a triceps injury last year and having surgery for it during the offseason.
The ESPN radio affiliate in Minnesota reports that Vikings running back Adrian Peterson is participating in team drills Wednesday during OTA workouts about four months after sports hernia surgery. The report says there's no live contact in OTAs, but it appears "he's full go" in this setting. "I'm pretty much 100 percent," Peterson said. "Me knowing my body, I would like to be a little stronger in some areas. But I'm feeling great." Peterson said he "definitely earned a lot more respect for your abdominal muscles" and has been ramping up his weight training after initially gearing exercises to reduce pressure on the area.
USA Today reports that new Seahawks receiver Percy Harvin has practiced as a slot receiver, outside receiver, running back and kick returner. Harvin sees similarities to how he was used under offensive coordinator Darrell Bevell in 2009 and 2010 in Minnesota, and also has had some flashbacks to his time at Florida, where he was the X-factor in the Gators' read-option offense. "We're always trying to find unique qualities in our guys, and then hopefully express that in our play," coach Pete Carroll said. "He's a different athlete, because not only is he so fast, but he's steel strong. Just really tough, physical for a guy who only weighs 197 pounds. We hope to see him catch the ball on the move, so he can use his stuff. That doesn't mean we give him the ball in the backfield just to hand it to him, we want to throw the ball to him all over the field. It's not going to change our football team in terms of what we want to do, we're just going to add him in and cut him loose, let him go."
