Rodrigo Palacio's last-gasp strike earned Inter Milan a 1-1 draw against Celtic in their friendly at Parkhead, but Hoops boss Neil Lennon was left with more to worry about ahead of Wednesday night's Champions League clash against HJK Helsinki.
Kris Commons, whose fine strike just before the break gave the home side the lead, hobbled off near the end leaving Celtic to finish the game with 10 men after they had used all their outfield substitutes.
Lennon had already seen striker Anthony Stokes carried off on a stretcher in the first half and that will be a concern ahead of the opening leg of their qualifier against the Finnish side in midweek.
On the plus side, the Parkhead boss will be heartened by his side's display even though Celtic go into their European campaign with only one win in six pre-season friendlies.
Lennon fielded a strong side although skipper Scott Brown was missing while right-back Mikael Lustig partnered Charlie Mulgrew at centre-back. There was a familiar look about Stokes and Gary Hooper in the Parkhead attack.
After a minute's applause for former Celtic striker Joe McBride, who died last week, Celtic enjoyed plenty of possession and pressure in the early stages.
There was a scare for Lennon in the 35th minute when Stokes was carried off on a stretcher after injuring his leg blocking a Esteban Cambiasso clearance on the touchline, to be replaced by Mo Bangura. However, there was something for the Celtic boss and the home fans to cheer five minutes from the break when his side forged ahead.
Mulgrew picked out Commons at the other side of the box with a free-kick and the Scotland international took a touch before sending a looping volley over the head of the helpless Handanovic.
Midway through the second half, Commons injured himself stumbling over the ball and hobbled around the pitch before going up the tunnel, leaving the home side with 10 men.
Inter took advantage with moments remaining. Celtic keeper Fraser Forster made a decent save from Cristian Divu's 25-yard drive, then another from Diego Milito, before substitute Palacio turned the ball in from a few yards out after a Marko Livaja cut-back.
