Joe Ledley could be included in Wales' Euro 2016 squad even if he is not fit enough to start the tournament, says assistant manager Osian Roberts.

The Crystal Palace midfielder fractured his leg on Saturday, playing against Stoke, and is a doubt for the campaign.

Manager Chris Coleman names his 23-man squad on 31 May and Wales play their first game on 11 June against Slovakia.

"If he misses the opening game, but is available for the others, we'd want Joe to be part of things," said Roberts.

"If we need to give Joe a little bit of extra time, we'll do so. He deserves that."

The 29-year-old, who was named in Coleman's provisional squad for the tournament in France, is highly unlikely to play in Palace's FA Cup final against Manchester United on 21 May.

Roberts added: "He's been a vital cog in the team for quite a few years and we hope he can recover in time.

"We'll have to wait and see how he reacts over the next couple of weeks. We're a stronger squad with Joe in it."

After facing Slovakia, Wales take on England in Lens on Thursday, 16 June before finishing the group stage against Russia on Monday, 20 June.

Minor fractures sometimes can take up to six weeks to heal, though the recovery time for more severe fibula injuries can be around three months.

It would be a significant blow to Coleman if Ledley was missing from his Euro 2016 squad, as Wales prepare for their first major international football tournament since 1958.

He played an integral part in qualifying for France, featuring in seven of the 10 Group B games, and offers valuable experience to the Welsh midfield.

Wales will travel to Portugal for a pre-tournament training camp on 23 May.

After the final squad announcement, Wales play Sweden away on 5 June, their last friendly before Euro 2016.
