Backup quarterback Tim Tebow practiced on a restricted basis this week and was questionable on the injury report for Sunday's game against Jacksonville. Tebow could be a game-time decision on whether his injured ribs are healed enough to back up starter Mark Sanchez. He sat out last week's game against Arizona when Greg McElroy replaced Sanchez and led a touchdown drive that gave the Jets a win. Coach Rex Ryan said he might reconsider his preference to activate only two quarterbacks for a game. "Certainly it would be a consideration to have three quarterbacks active," Ryan said Friday, according to a New York Daily News report. Ryan did confirm that said Tebow won't play on special teams.
