(AP) — The Carolina Panthers signed Kyle Trask as a third quarterback on Sunday with Hall of Fame game hero Haynes King expected to miss time with a hamstring injury. Trask gives the Panthers a third QB behind starter Bryce Young and backup Kenny Pickett. Trask has familiarity with Panthers offensive coordinator Brad Idzik, having spent the last three seasons with the Tampa Bay Buccaneers. The Atlantic Coast Conference Player of the Year last season, King was 21 of 34 for 180 yards and two touchdowns. Panthers coach Dave Canales said King strained his hamstring on the final play and will not play Saturday against the Buffalo Bills.
