Daniel Sturridge struck in the third minute of stoppage time on his Bolton debut last night to inflict a third straight league defeat on relegation-haunted Wolves.
Former Chelsea striker Sturridge finished coolly after a howler from Ronald Zubar as Mick McCarthy's men slumped to the foot of the table, deeper into the mire.
The visitors had perhaps the best chance of a scrappy first half, but star winger Matt Jarvis could only roll a shot feebly wide when clean through on goal.
The hosts responded and Johan Elmander forced a good save from Wayne Hennessey, who then did brilliantly to deny Kevin Davies.
Wolves, who had Ireland striker Kevin Doyle back in their line-up after illness , were making life difficult for Bolton.
The hosts had the better of the second half, but Wolves came close to scoring in 87th minute when Doyle's shot looped over Jussi Jaaskelainen only to come back off the post. Then Sturridge struck.
