Major injury blow for England as Cowan-Dickie ruled out of Six Nations

Cowan-Dickie suffered an ankle injury against Northampton on January 7 and, having been ruled out for an unspecified period of time, Baxter gave a timeline for his recovery that prevents him from taking part in the championship.

The news is a blow to England, whose resources at hooker have been further depleted by Jamie George's concussion and a knee problem incurred by George McGuigan.

Unless George recovers in time for the opener against Scotland on February 4, it means the uncapped Jack Walker will start in the number two jersey, with three-cap international Tom Dunn providing bench cover.

"The length of Luke's injury means he should be back before the end of the season. The challenge will be whether it's one or two weeks before the end of the season," Baxter said.

"It's not going to be a big chunk of the season that he gets back available for."

Baxter revealed that full-back Stuart Hogg has returned to full training following his battle with a heel injury and has been training with Scotland this week.

Hogg is in line to make his comeback after five weeks out when Exeter clash with Gloucester on Saturday.
