Tennessee Titans tight end Delanie Walker is expected to be a game-time decision for Sunday's game against the Oakland Raiders, according to ESPN's Adam Schefter.
The Titans' leader in receiving yards will test his hamstring in pregame warmups before a determination is made.
Walker was listed as questionable this week and only managed a limited appearance in practice on Thursday.
He has proven to be a necessary safety valve for sophomore quarterback Marcus Mariota, and his absence would have an impact on the Titans' passing game.
