Zlatan Ibrahimovic will be out for two to three weeks after suffering a hamstring injury in the first leg of Paris Saint-Germain's 3-1 Champions League win over Chelsea. The Swedish striker reared up after an innocuous-looking challenge with David Luiz in the 68th minute and lay on the turf in clear discomfort before receiving attention from medical staff. Ibrahimovic's grimace as he left the pitch told its own story, and the 32-year-old will miss the return leg at Stamford Bridge on Tuesday. PSG coach Laurent Blanc confirmed that Ibrahimovic is likely to need a period out of the game. 'He felt some pain in his muscle, we'll check in detail tomorrow. It's an injury that will require some time of rest,' he told French TV.
