Defender Matthew Boyd and ruckman Tom Campbell have been cleared for selection ahead of this week's season opening game against Collingwood at the MCG on Friday night. 

Medical Services Manager Chris Bell said a severe laceration received by Boyd in the Bulldogs' JLT Community Series win over Gold Coast had healed well.

"Boyd sustained a severe laceration to his ear in the game. The stitches have since been removed and the ear's healed really well. He's back into full training mode and available to play this week."

Meanwhile, Tom Campbell, who rolled his ankle in an intra-club match several weeks ago, has also recovered well, said Bell.

"Tom's completed the final stages of his rehabilitation following his ankle injury. He's resumed full training and will be available this week."

Campbell's fellow ruckmen Jordan Roughead and first-year player Tim English are also in recovery mode.

Roughead sustained an unusual injury - an avulsion of three tendons to the inside part of his knee - in the Bulldogs opening JLT match against Melbourne, but his rehabilitation is progressing well.

"Jordan has progressed well from his injury. He started running today and he'll be systematically progressed over the next couple of weeks, so we can be more accurate with his return to play timeline in the next few weeks. 

English pulled up sore after the Bulldogs' VFL recent hit-out against Richmond and will be given time to recover.

"Tim has sustained some minor bone soreness to the inside part of his shin following the last VFL game. He'll be managed conservatively, and that will involve a period of time off legs, and he'll be assessed in the coming days [with a view] to return to some training."
