50 Anthony Walker LB

Walker (groin) is active for Sunday's game against the Texans.

Walker dealt with a minor groin issue that kept him limited in practice heading into Week 4, but he's good to go while Zaire Franklin and Matthew Adams provide additional depth at linebacker.

Walker (groin) is questionable for Sunday's game against the Texans.

Walker was limited in Friday's practice due to a groin injury of undisclosed severity. It remains to be seen whether the linebacker will suit up Week 4, but if Walker were to miss any time it could propel undrafted rookie Skai Moore into the starting lineup.

Walker had nine total tackles and defended a pass in Sunday's loss at Philadelphia.

Walker play 73 of the defense's 83 snaps, which is nearly double the total he logged during the first two weeks. Meanwhile, backup middle linebacker Skai Moore didn't play a snap on defense. It looks like Walker is back to full speed after missing a month during the preseason due to a hamstring injury. He could be a reliable source of tackles with his full-time return to the lineup.

Walker had five total tackles and a QB hit in Sunday's loss to the Bengals.

He played just 23 snaps (42 percent of the defense's plays), however. He was likely eased back into action after missing a month during the preseason due to a hamstring injury. However, it's worth watching his snap count as backup Skai Moore had an impressive preseason (although Moore struggled in pass coverage Sunday).

Walker was a full participant in Thursday's practice.

Walker missed over a month due to a groin injury, practicing fully for the first time Thursday. While the 23-year-old is listed as the top middle linebacker on the Colts' first regular-season depth chart, Walker should be considered questionable to start in Sunday's season opener against the Bengals.
