Rory McIlroy's made a good start to his first golf tournament since returning from a rib injury.
The former world number one finished the first round at the WGC Mexico Championship 3-under-par - just a shot off the top of the leaderboard.
Speaking to Sky Sports News, McIlroy says he's not been troubled by the problem he picked up in South Africa in January.
Rory's return? T7.
