With the news earlier that running back Peyton Hillis will do some work (and that he looked good) in practice, there's a lot more going on for the Cleveland Browns in regards to injuries. According to Mary Kay Cabot of Cleveland.com, there are multiple players limited or not practicing at all on Wednesday.
The biggest news is that the two receiving targets, WR Mohamed Massaquoi and tight end Benjamin Watson, are sitting out of practice with concussions. Both of the receivers suffered concussions before the second half, near the end of the first half. Massaquoi was hurt going up for a pass over the middle, and it's still unclear when Watson suffered his injury, but they'll need to pass an exam before they can practice again, let alone play.
Also of note is linebacker Scott Fujita, and the fact that he's back in action, participating in full practice on Wednesday. He sat out Sunday's game against the Seattle Seahawks due to a concussion he suffered against the Raiders. He was sent home multiple times during the week leading up to the Seattle game with post-concussion symptoms. Barring some kind of set back in practice, Fujita is expected to play on Sunday against the 49ers.
Wide receiver Carlton Mitchell is reportedly going to be active, as well. He's only been active for one game this season, and played only special teams in that time. According to Cabot, Mitchell should be prepared to play on offense as well as special teams.
Kicker Phil Dawson and offensive lineman Shaun Lauvao will be limited in practice, as well.
