Barnet boss Dean Brennan says striker Kabongo Tshimanga will be out "for a while" with a knee injury.

Tshimanga, 29, is League Two's leading goalscorer, with 10 goals in 13 appearances.

He played 80 minutes in the 1-1 draw at Crewe Alexandra on Saturday but Brennan admitted the forward was carrying the injury throughout, having sustained it last week against York City, and will now be rested for an unspecified period.

"He should never have played, but I asked him to play," Brennan told BBC Radio London.

"He'll get a break now, so you won't see him for a while because he's got a knee injury.

"To be fair to him, he soldiered through for us and played.

"Even at 1-0 [up], you can't take him off the pitch. I'd never take him off, ever, in a month of Sundays, but he wasn't 100% fit."

Brennan also said two players signed from non-league football, who came off the bench at Crewe, need to "get the detail right".

Isiah Noel-Williams and Jack Maskell have both largely been used as substitutes since joining and the Bees boss says they are still adapting to League Two level.

"When they come on, they've got to understand what we want from them," he said.

"They're jumping up a few levels. Noel-Williams was at Hemel [Hempstead Town] last year, in National League South, and young Maskell was playing at Darlington, which is National League North, so it's a big jump for them lads.

"They've just got to get the detail right."
