The Ospreys will be without captain Justin Tipuric in the final weeks of the season as they bid to secure Champions Cup rugby for next season.
Toby Booth's side currently sit four points behind Cardiff with two games left - meaning that, with a Judgement Day clash between the two sides on the final day of their season on April 22, the Welsh Shield and entry into European rugby's top tier could come down to the wire.
Unfortunately, an injury picked up in the first half of the Champions Cup last-16 defeat to Saracens means the Ospreys will be without their influential openside for the games against Edinburgh on April 15 and then Cardiff. However, Booth says he does not think the injury will be serious enough to cast doubt on the back-rower's involvement in any of the World Cup training camps this summer.
