Alisha Joyce is set for her Wales comeback just five months after giving birth to her son Ralphie.
Joyce is named among the replacements to face reigning world and Six Nations champions England at Ashton Gate on Saturday (14:15 BST), 562 days since her and her partner Jaz Joyce last played together for Wales.
The 28-year-old Bristol Bears flanker has only had half an hour of rugby in the Celtic Challenge this season.
But her physicality in training has impressed Wales head coach Sean Lynn.
"What I love about Alisha, she's been chomping at the bit to put that jersey back on since she's been into camp," he said.
"She's been outstanding in training, so it's exciting to see her coming off the bench."
