William and Mary quarterback Michael Graham will miss Saturday's upcoming game at Delaware with an undisclosed illness, the school said in a release Wednesday.

Graham, a redshirt sophomore from Charlottesville, had started the past two games and had provided some stability at the position after an uneven start to the season. He will be replaced by either Mike Paulus, who started the first three games, or Brent Caprio.

"We will miss having Mike Graham on the field Saturday," Tribe head coach Jimmye Laycock said in a statement. "But the next man in line will have to step up to the challenge."

Laycock added that he was confident that either Paulus or Caprio could provide the necessary leadership.

Graham, a recruited walk-on, had completed 36 of 66 passes for 560 yards and three touchdowns, with one interception. He helped the Tribe to last week's 20-16 win at Villanova. He was given his first start the previous week, in a 20-14 loss to James Madison. He earned the start following a solid relief appearance in the second half against New Haven on Sept. 17.

It's the second consecutive season that the Tribe has experienced something of a quarterback carousel. Last year, injuries forced the team to use four different quarterbacks on the way to a share of the CAA title.

The juggling at the position this season is more tied to consistency of play. Paulus and Caprio were inconsistent in the first 2 1/2 games, prompting Laycock to give Graham an opportunity.

Paulus, the senior transfer from North Carolina who saw time a year ago, is 18-for-48 for 183 yards and one touchdown, with an interception. Caprio is 5-for-12 for 44 yards and two interceptions.

Saturday's game pits the two teams that tied for the CAA title last season. Both are 3-2 overall, 1-1 in the CAA.
