Both players were injured in the Jets' 38-3 loss to the Buffalo Bills on Monday night.
Coach Rex Ryan says Tuesday that Amaro, who leads NFL rookie tight ends with 34 catches for 291 yards receiving, is going through the NFL's concussion protocol. Ryan wouldn't confirm whether Amaro actually has a concussion, but the rookie's status for the Jets' game against the Miami Dolphins next Monday night is uncertain.
Ryan says Wilkerson's toe injury "doesn't look great," but hopes it improves so he can play. Wilkerson missed the second half with the injury after being hurt late in the second quarter.
