Temple safety Amir Tyler underwent surgery Friday for an unspecified upper-body injury, according to coach Rod Carey.

The 6-foot, 205-pound team captain had the procedure during the Owls’ bye week and is expected to be sidelined for “the next couple weeks,”

Tyler, a graduate player, is Temple’s leading tackler through six games with 47 total tackles, including three for losses. His season-high 12 tackles came in a win against Memphis on Oct. 2.

Temple’s defense will have big shoes to fill in Tyler’s absence. He was a vital piece of the American Athletic Conference’s second-ranked secondary; only No. 2 Cincinnati is allowing fewer yards per pass attempt.

Redshirt freshman M.J. Griffin, who is second on the team in tackles with 35, will continue to hold down the other starting safety position. Redshirt junior Jalen Ware and freshman Alex Odom would likely be next in line at that position, based on the most updated depth chart.

The Owls return to action Saturday night at South Florida .
