NORMAN — University of Oklahoma senior defensive lineman R Mason Thomas was named as one of 17 semifinalists for the 31st Chuck Bednarik Award for the Outstanding Defensive Player of the Year, the Maxwell Football Club announced.

Thomas has started eight of nine games this season and totaled 23 tackles, including 9.5 for loss and 6.5 sacks, two QB hurries, one pass breakup, two forced fumbles, and one fumble recovery that he returned 71 yards for a touchdown.

He has registered 20 of his tackles (8.5 TFLs and all 6.5 sacks) over the last six games and has 14 tackles (6.5 TFLs and 5.5 sacks) in OU's five SEC contests, despite playing only the second half against Auburn and half of the first quarter at Tennessee.

In OU's 24-17 win over Auburn on Sept. 20, Thomas notched a then-season-high four tackles (all solo) and 2.0 sacks.

His second sack was a game-sealing safety that made the score 24-17 with 1:06 remaining in the fourth quarter, and his first sack came on the second play of the second half (his second play of the game after he sat out the first half due to a penalty from OU's previous contest).

He was named the SEC Defensive Lineman of the Week following his performance.In the Sooners' 33-27 win at Tennessee on Nov. 1, Thomas scooped a fumble with one hand while engaged with a blocking tight end, stiff-armed the opponent for 25 yards and eventually broke free for a 71-yard TD.

Thomas injured his leg on the return and missed the rest of the game.The Fort Lauderdale, Fla., product has played in 41 career games and made 19 starts, compiling 61 tackles, 25.5 tackles for loss, 17.0 sacks, four forced fumbles, three fumble recoveries, three pass breakups and 16 QB hurries.

He has been especially productive over his last two seasons, totaling 46 tackles, including 22.0 for loss and 15.5 sacks. All four of his forced fumbles, three of his fumble recoveries and 13 of his QB hurries have come in the last two seasons.
