Johnson missed six months of last season's campaign through injury

Warrington centre or second rower Paul Johnson will miss the rest of the season after suffering a cruciate knee ligament injury.

Johnson was injured during the second half of Warrington's 40-34 Challenge Cup defeat at St Helens on Saturday.

The 29-year-old will need a full knee ligament reconstruction.

The setback comes a day after Wolves full-back Stuart Reardon was also ruled out for the rest of the season with a ruptured Achilles tendon.

Johnson, a Great Britain international, created two tries for Chris Hicks in his side's defeat by Saints at the weekend.

Both Johnson and Reardon have been key players for Wolves this campaign, helping the club into the top six.
