The Browns placed rookie running back Terrance West and five other players on the non-football injury list today.
But West, a third-round pick in this year's draft, took to Twitter to assure fans he isn't dealing with anything serious.
"I'm healthy, ready to go," West tweeted this evening. "(NO WORRIES)
West also shot down the notion he might have failed the Browns' conditioning test.
The Browns' moves, included on the NFL's official list of transactions, were made on a day when rookies, injured veterans and quarterbacks reported to camp. The first full-squad practice will be held Saturday morning.
The NFI list is designated for players who suffered injuries away from the team. Players on the list remain on the roster and can practice as soon as they're cleared.
In addition to West, defensive end Billy Winn, inside linebacker Tank Carder, offensive tackle Chris Faulk, defensive tackle Jacobbi McDaniel and guard Jeremiah Warren are on the NFI list.
The Browns also claimed undrafted rookie offensive tackle Abasi Salimu off waivers from the St. Louis Rams. They waived defensive back Royce Adams, linebacker Brandon Magee and wide receiver Conner Vernon.
