(CNN) -- Rio Ferdinand could be fit for Manchester United's second-leg Champions League clash with Arsenal after scans revealed he had not cracked a rib.
A dazed Ferdinand is helped from the field after damaging his ribs against Arsenal on Wednesday.
There were fears that the England international defender would be sidelined for several weeks after he was forced off during United's 1-0 first leg victory at Old Trafford on Wednesday.
Ferdinand was in obvious discomfort after bravely attempting to clear a dangerous Cesc Fabregas free-kick and going down under a ruck of players.
He will miss United's Premier League game with Middlesbrough on Saturday but manager Ferguson is confident he could be fit to face the Gunners at the Emirates.
"It's good news with Rio," he told Press Association.
"It is not a cracked bone, he had a bit of bruising on the lung which was why he was coughing up blood but there has been nothing since then," Ferguson said.
"Hopefully we can get him ready for Tuesday, he seems almost back to normal. But he won't play tomorrow."
Northern Ireland international Jonny Evans came on for Ferdinand for the final few moments and he is set to deputize for the trip to the Riverside to face relegation battlers Boro.
United will make several changes ahead of the crucial return leg against Arsenal, but know that victory on Saturday will take them six points clear of nearest title rivals Liverpool who are playing Newcastle the following day.
United have been hard-hit by injuries to established defenders this season, but Wes Brown, who can play in central defense or full-back, is fit again after a long-term injury and is included in the squad for the Middlesbrough match.
But Ferguson will be hoping Ferdinand can resume his formidable partnership with Nemanja Vidic at the heart of their defense for a testing night against Arsene Wenger's men on Tuesday.
