Lee Johnson has provided an update on the fitness of Lynden Gooch.
The American forward, who has been impressed at wing-back, was replaced at half-time during Sunderland’s 2-1 win over Plymouth Argyle on Saturday.
Speaking post-match, the Head Coach admitted he faces an anxious wait to determine the full extent of the injury.
“Lynden went for a header and landed funnily - he almost did the splits,” Johnson said.
“It's a groin strain and he felt it enough to come off.”
He continued: “Sometimes they settle down pretty quickly and sometimes they are bad - there's no real in-between - he will probably be fit for training on Tuesday or out for three or four weeks.
“Doyle was dragged out a bit once Goochy went off, and Leon was playing out of position at wingback, Embleton out of position, Winchester out of position - that's credit to them and to the work that we do.
“They are tactically adaptable and fighting for the cause even when they are in uncomfortable positions. It’s third game in a week at home, another really tough game and we’ve got seven points from nine.
"We wanted nine and probably should have had nine with the level of performance, but I am proud of the lads really.”
