The Arizona Cardinals placed rookie Troy Niklas on season-ending injured reserve and used a mulligan to add a tight end on Tuesday.

Matthew Mulligan, a six-year NFL veteran tight end and a native of Enfield, Maine, was added to the Cardinals’ roster to fill the spot left by Niklas’ injury.

Niklas, selected in the second round of the 2014 NFL Draft from Notre Dame, came back from an early season ankle injury but suffered a high ankle sprain on Sunday in the Cardinals’ 14-6 win over the Detroit Lions. He played in seven games and had three catches for 38 yards.

Mulligan, released by Chicago on Sept. 16, saw action in two games and started one for the Bears.

Mulligan, a former University of Maine standout, was signed by the Bears back in April after finishing a one-season stint with the New England Patriots.

The 29-year-old Mulligan first signed with Miami as an undrafted free agent in 2008 and has seen game action with the New York Jets, the St. Louis Rams and the Patriots.

Mulligan, who is a blocking specialist, has played in 67 career NFL games. He has made 16 receptions for 160 yards and two touchdowns, including one with the Patriots last season.

He also has two kick returns for 28 yards and one special-teams tackle.

The Cardinals are 9-1 and in first place in the NFC’s West Division. They will play the defending Super Bowl champions Seahawks in Seattle at 4 p.m. Sunday.
