Arsenal goalkeeper Petr Cech forced off with leg injury

Arsenal goalkeeper Petr Cech was forced off with a leg injury during his side's 3-1 defeat at West Bromwich Albion on Saturday.

The Czech veteran went down in the 35th minute after initially pulling up when attempting to sweep a left-footed pass away to Shkodran Mustafi.

Cech called for treatment and was replaced in goal at The Hawthorns by Colombia international David Ospina, who has been Arsenal's first-choice goalkeeper for cup matches this season.

Ospina has not started a Premier League match for the Gunners this term, last featuring from the outset in a league game in April 2016, a 3-3 draw at West Ham United.

Saturday's result has left Arsenal fifth in the Premier League table, five points behind fourth-placed Liverpool.
