Reacted well when Yohan Cabaye's first-half shot took a wicked deflection off David Fox and could not be blamed for his defense being split for Ba's equalizer, but nearly cost his side when he completely failed to claim a free kick just after halftime.
Careered up and down the left flank in support, as is his wont, but Gabriel Obertan looked to pose him problems in his own half.
Could have been exploited more by Jonas Gutierrez at the back but put in a shift to support on the flank.
Showed good awareness to head away under pressure deep in his own penalty area midway through the first half. Had trouble dealing with Ba now and then and was taken out by Gosling for the red card.
Making his comeback after several weeks out injured, the American might have done more to prevent Shola Ameobi from delivering his assist for Ba's second, but coped adequately overall.
In the right place at the right time to grab the opener from the disputed corner but otherwise was not at his best. Never really had the space to cut open the Newcastle defense and was replaced with just under 10 minutes to go.
A typically energetic effort from the midfielder, with some good link play with Tierney on the left wing, but ultimately without much end product. Replaced with 15 minutes to go.
An industrious effort on the right of midfield for the Welshman, capped off by an excellent cross to set up Morison's strike.
Gave away a few fouls in trying to deal with Cabaye and wasteful in trying some long shots.
A typically heroic performance from the captain, restored to the starting lineup. His doggedness ensured that he claimed the vital second goal in a period when Norwich were up against it, and his contribution in the build-up to Morison's soon after should not be ignored. Best of all, though, was his stooping header for the final goal that powered into the top corner. The key for Norwich.
Found it difficult to have his usual impact on the game at times and seemed a little crowded by playing alongside Holt. When he did hold the ball up, he was prone to making the wrong decisions with it. However, his scoring instincts remained strong, with an excellent run to meet Crofts' cross with a fine header to make it 3-1.
Harshly judged to have carried the ball over the line for the corner that led to Hoolahan's opener and could hardly have done anything about the other Norwich goals.
An admirable performance filling in at center half from the right back, keeping Morison quiet for most of the game and acting as a calming influence on his young partner Perch.
Did a decent job for much of the match but was beaten by Holt on the ground and in the air on a few occasions.
Put in some effort to slow Surman's progress on the left of midfield but allowed Tierney far too much freedom on the overlap.
Should have conceded a penalty for a fairly clear handball in the first half and was conspicuous by his absence when Crofts ran into space on his flank to set up Morison.
A quiet afternoon for the stand-in captain, failing to do enough to trouble Kyle Naughton on the visitors' left.
Not the midfielder's best afternoon. He fluffed a great chance on the volley in the first half as well as picking up a booking, before receiving a straight red midway through the second half for serious foul play as he bulldozed Russell Martin.
Showed signs of being a thorn in left-back Marc Tierney's side but was too often wasteful and ponderous with the ball at his feet. Replaced with 10 minutes left.
Threatened to make a real difference for Newcastle but never quite stamped his authority on the game. His defense-splitting assist for Ba's equalizer showed excellent vision and his first half deflected shot nearly bent in.
Provided a glorious assist for Ba's second in an uncharacteristic moment of playmaking genius.
Showed a willingness to drop deep to help in the build-up of play and made no mistake when put through one-on-one to equalize. His first touch in taking his second was sublime football and evidence of a top-class striker.
