Stevenage are waiting to find out the extent of Ronnie Henry’s injury suffered in a pre-season friendly.
The defender limped off on the quarter-hour mark in their 1-0 defeat to Barnet, after a heavy challenge.
Henry returned to the Hertfordshire club after a 2-year spell at Luton Town. He made 280 appearances for Boro in his first spell at the club and his return, earlier this month, was popular amongst fans.
Charlie MacDonald, who used to play for Stevenage, scored the only goal as he capitalized on a mistake from Boro substitute Jo N’Guessan.
New signings Chris Whelpdale and Charlie Lee made their first start for the club since signing last week.
Stevenage play Millwall at the Lamex in their next pre-season friendly, on Saturday.
