Brigham Young Cougars quarterback Tanner Mangum (12) is sacked by Utah Utes linebacker Cody Barton (30) and defensive end Kylie Fitts (11) in the third quarter at LaVell Edwards Stadium in Provo on Saturday, Sept. 9, 2017.

PROVO — Going into Saturday’s game against No. 10 Wisconsin, the status of BYU quarterback Tanner Mangum remains uncertain.

Mangum suffered a left ankle or left foot injury on the Cougars’ final offensive play in last Saturday's home 19-13 loss to Utah.

While BYU does not comment on injuries unless they are of the season-ending variety, Mangum reportedly is wearing a protective boot on his foot and has undergone an MRI.

If Mangum is unable to play, sophomore Beau Hoge is expected to get his first career start. The 6-foot-1, 208-pounder from Fort Thomas, Kentucky, redshirted last season after seeing action in three games in 2015 as a freshman.

Offensive coordinator Ty Detmer acknowledged Monday on the “Coordinators’ Corner” radio show that Mangum "got rolled up on" on that play against Utah and that he received treatment Sunday. “But as far as I know right now, everything is ready to go," Detmer said.

On Tuesday, linebacker Butch Pau’u was asked if Mangum participated in that day’s practice. Pau’u declined to answer, saying that it was a question for Detmer to address.

More about Mangum’s situation could come to light as offensive players and coaches will be made available to the media Wednesday.
