J. J. Watt DL HOU 1 Hr

Watt did not participate in Wednesday's practice due to a thigh injury, the Houston Chronicle reports.

We suspect this more of a rest day for Watt than a significant injury, but it's something to monitor nonetheless.

Arian Foster RB HOU 2 Hrs1 Comment

Head coach Bill O'Brien said he is only thinking about this week's game against the Cowboys when asked about reducing Foster's (hamstring) workload in preparation for next Thursday's game against the Colts, the Houston Chronicle reports. "Every decision you make, regardless of when the next game is or who the next game is, is about that game and how are you going to try to win that game. This game on Sunday is going to be a big challenge for our team," said the coach.

With two games coming up in five days, the thought of keeping Foster fresh for the division match against the Colts is something O'Brien will not allow himself to contemplate.

Theo Riddick RB DET 3 Hrs

Riddick (hamstring) did not practice Wednesday, the Detroit News reports.

Neither did Joique Bell (concussion), and if one or both of the two backs are unable to suit up this weekend, then newcomer George Winn could be pressed into action in a reserve role behind Reggie Bush.

Vernon Davis TE SF 3 Hrs

Davis (back) didn't take part in practice Wednesday, the Sacramento Bee reports.

Davis relayed after drills that he's able to move about better than he did Sunday, when he suffered his current back injury. However, the back spasms haven't subsided entirely, spurring the tight end to term himself "day-to-day," according to Matt Maiocco of CSN Bay Area. The 49ers' current picture at tight end is clouded, with Vance McDonald dealing with a knee concern, meaning interested parties should keep a close eye on the situation as the week continues.

Chandler Jones DL NE 3 Hrs

Jones (shoulder) was limited at Wednesday's practice, ESPN.com reports.

Jones, who injured his right shoulder in Monday's loss to the Chiefs, checks in with 17 tackles and 2.5 sacks in four games out of the gate.

Frank Gore RB SF 3 Hrs

Gore (back) practiced fully Wednesday, Matt Barrows of the Sacramento Bee reports.

Gore has never before dealt with a back injury, but the ailment didn't stop him from fitting in every rep in the first practice of the week. His upcoming opponent, the Chiefs, have allowed a robust 5.5 YPC to opposing running backs this season, which places the 49ers' lead back in good fantasy standing in Week 5.

Rob Gronkowski TE NE 3 Hrs

Gronkowski (knee) was listed as a full participant at Wednesday's practice, the Patriots' official site reports.

It's notable that Gronkowski is practicing fully at this stage of the week, after previously being listed as limited. Gronkowski was on the field for 31-of-50 snaps on offense this past Monday, but his full participation at practice Wednesday could foreshadow the tight end seeing a higher percentage of snaps Sunday night against the Bengals.

Michael Crabtree WR SF 3 Hrs

Crabtree (foot) practiced in full Wednesday, Matt Barrows of the Sacramento Bee reports.

After leaving Sunday's win against the Eagles for a short time due to a foot injury, Crabtree fended it off by hauling in five balls (on eight targets) for 43 yards. The 49ers' corps of receivers could be without Vernon Davis (back) and Vance McDonald (knee) in Week 5 against the Chiefs, thereby affording Crabtree plenty of looks from Colin Kaepernick. Crabtree has received a combined 28 targets over the last three games.

Calvin Pryor DB NYJ 4 Hrs

Pryor (bruised thigh) practiced Wednesday, ESPN.com reports.

Though he was limited during Wednesday's practice session, the report suggests that Pryor should be ready to go Sunday against the Chargers.

Deone Bucannon DB ARI 4 Hrs

Bucannon wasn't listed on the Cardinals' injury report Wednesday, FOX Sports 910 Phoenix reports.

Bucannon emerged from the Cardinals' previous game in Week 3 with a mild foot sprain, but afterward, coach Bruce Arians expressed optimism that the bye week would provide enough recovery time for the rookie safety to play this coming Sunday at Denver. Indeed, that has come to pass, as Bucannon attempts to build upon a decent start to his NFL career, with 13 tackles (12 solo) in three outings.
