England star James Haskell will play a "big part" during the Six Nations, according to Wasps director of rugby Dai Young.
Haskell was sidelined with a toe injury in the second half of last year and played less than a minute on his return earlier this month.
The 31-year-old was knocked out in a tackle during Wasps' 22-16 win over Leicester Tigers in the Premiership on January 8.
But Haskell is expected to face Zebre in the European Champions Cup on Sunday, a good sign ahead of the Six Nations starting next month.
"James will play a really big part in England's campaign," Young said, via The Telegraph.
"He has trained fully with us for four weeks and has come through with flying colours.
"He has passed all the protocols to return to play and will start at either six of seven against Zebre. He is busting to get out there."
England begin their Six Nations campaign with a clash against France at Twickenham on February 4.
While Young acknowledged Haskell would have liked to play more, he expects the 70-time international to perform well.
"In an ideal world, of course, he'd rather have a bit more game time under his belt but he is experienced enough to cope," he said.
"He has been round the block enough for it not to faze him.
"Sometimes it is more of a confidence thing for a player that has been out and that's not something James struggles with. He'll be all right."
