Arsenal manager Arsene Wenger has confirmed that Aaron Ramsey is definitely out of this weekend's FA Cup clash with Middlesbrough, but his hamstring injury is only a grade one tear and should keep him sidelined for just two weeks.
Ramsey pulled up with the problem just nine minutes after coming on a as a substitute against Leicester City on Tuesday night, that latest in a succession of muscle injuries that continue to catch Arsenal medical staff cold.
Wenger admitted as much in his press conference this morning, conceding that they are yet to work out why Ramsey is so susceptible to picking up injuries even when considered close to full fitness.
Arsenal need to get this issue sorted
In his address ahead of Sunday's fifth-round clash against Boro the Gunners boss conceded that Ramsey is a long-term concern, while Alexis Sanchez is also short the tie with a knock to his knee.
Wenger said: "It's not a major injury. It's a grade one. There is an underlying reason that is medical or bio-mechanical, because he's a guy who is serious, works hard. We haven't found the underlying reason."

Gunners fans tired of familiar injury complaints
Ramsey has already missed nine games this season with hamstring injuries, while the Welshman was also frustratingly sidelined for three months last season just as he'd hit top form.
Wenger will surely err on the side of caution rather than rushing Ramsey back into action, so don't expect to see the playmaker until mid-March at the very earliest.
Sanchez meanwhile is another player Wenger shouldn't risk this weekend, after playing the Chilean superstar against Leicester City when he looked far from 100% fit.
Danny Welbeck, Olivier Giroud and Tomas Rosicky are players likely to feature in the pair's absence this weekend, while Gabriel Paulista is in line for his debut just over a month after completing a £10 million move from Villarreal.
