McGuinness’ quarterback battle twisted last week when senior Jennings Jarman suffered an ankle injury early in the Irish’s scrimmage at Lawton MacArthur.
Jarman was held out of the rest of the scrimmage for precautionary reasons and may not play in Thursday’s scrimmage at the Mustang Preview.
That would leave junior Jacob Mullins to receive the bulk of the plays.
“They both know how to operate our system, which is what we like,” McGuinness coach Justin Jones said. “The thing I like about it was we were able to respond when a guy gets injured. The mentality didn’t change for us.
“We had a lot of things to worry about. Lawton Mac’s a really good football team, they put it on us but we learned a lot from it. We’ve got to correct our mistakes and get ready to go.”
Jones said there’s a good chance McGuinness plays both quarterbacks in next week’s season opener against top-ranked Shawnee.
“In my opinion right now, there’s not a clear-cut favorite,” Jones said. “To be honest with you, we’re way up in the air with it all. It’s a day-by-day thing with us. Come Monday or so when we’ve got to make a decision as far as how the reps go, then we’ll make that decision.”
