Burns is the third Terrapins starting quarterback to suffer a season-ending injury this year.
After starter Danny O'Brien decided to transfer to Wisconsin this past summer, the Terps lost starter C.J. Brown to a torn ACL, Perry Hills to a torn ACL last weekend against North Carolina State and now Burns, a converted wide receiver who moved back to his original position just to help out the position.
As Maryland prepares to visit Boston College on Saturday, it does so with only one eligible scholarship quarterback on its roster -- true freshman Caleb Rowe.
The school also announced that wide receiver Marcus Leak will miss the rest of the season with a fractured toe.
"Obviously this is something that is very tough on both of these guys and our team," coach Randy Edsall said in a prepared statement. "I feel for both Devin and Marcus because I know they want to be out there competing. Both have been team-first guys who have done everything we have asked, and we will be here to support them as they begin the rehab process."
Burns played in three games this season. His most extensive playing time came when he took over for Hills in the 20-18 loss to NC State, when he rushed for 50 yards and one touchdown. He also completed 3-of-4 passes for 47 yards and helped lead the Terps on three second-half scoring drives.
Leak had played in all seven games and ranks second on the team in receptions (23), receiving yards (393) and touchdown receptions (two). He turned in his best performance of the season against the Wolfpack, notching a career-high 94 yards on four receptions, including a career-long 47-yarder from Hills.
Rowe now will have to start against BC.
Rowe entered the game last week and burned his redshirt with 32 seconds left to direct Maryland's 2-minute offense. Rowe moved the Terrapins 61 yards in three plays, sandwiching passes of 17 and 33 yards with an 11-yard run. That set up a 33-yard field goal attempt that would have won the game, but freshman Brad Craddock's attempt clanged off the left upright.
Rowe became the 13th true freshman to play for Maryland this year.
The depth chart is a question mark beyond him.
