University of Maine junior quarterback Joe Fagnano suffered a right leg injury late in the first quarter of Saturday’s game at James Madison University in Harrisonburg, Virginia, and was taken to a local hospital for X-rays.

X-rays were negative but he did not return to the game.

“I spoke with our trainer, Ryan Taylor, and I believe it is a high ankle [injury],” said UMaine head coach Nick Charlton. “I don’t know enough about it at this point. Joe is in a [protective] boot right now. Initially we were concerned it was something else. But I can’t diagnose that right now,” said Charlton, who added that Fagnano will be out but that it’s not known for how long.

Redshirt freshman Derek Robertson, a native of Yonkers, New York, who played at Bridgton Academy, replaced Fagnano.

“Derek was put into an adverse situation. At times he did some things well and other times he did not. He has to play better and I have to coach better,” Charlton said. “He is very intelligent. He knows the offense. It’s about him understanding and recognizing coverages which goes beyond just his performance. You’ve got 10 other guys that have to be doing the right thing.”

Robertson wound up completing 8 of 22 passes for 88 yards and his first career touchdown. He was intercepted once on a tipped ball and it was returned for a touchdown. He was also sacked three times.

He made his college debut in a 44-17 loss to Villanova in April and completed all four of his passes for 28 yards.

Fagnano was injured trying to complete a pass to Devin Young with three minutes left in the first period. The pass was incomplete but James Madison was called for holding on the play.

Fagnano completed four of six passes for 31 yards before sustaining his injury.

The Williamsport, Pennsylvania, native was an All-Colonial Athletic Association second team selection this past spring when he completed 67 of 116 passes for 795 yards and eight touchdowns.

He also ran for two touchdowns.

In last week’s 34-24 loss to No. 5 Delaware, Fagnano completed 24 of 41 passes for 305 yards and two touchdowns. He was intercepted twice.

Fagnano started his 12th straight game on Saturday.

He stepped in during the sixth game of the 2019 season when Chris Ferguson suffered a season-ending foot injury.

He completed 121 of 184 passes for 1,835 yards and 17 TDs. He was intercepted just three times.

He was chosen the league’s Rookie of the Week on two occasions.

UMaine hosts Merrimack College for a non-conference game Saturday at noon.

Merrimack, still in its probationary period in Division I after moving up from Division II, is 2-0 after stunning Holy Cross 35-21 on Saturday. Holy Cross had upset Football Bowl Subdivision team University of Connecticut 38-28 the previous week.

UMaine will then travel to play FBS school Northern Illinois on Sept. 25 and will have a weekend off before returning to CAA play against visiting Elon on Oct. 9.
