Sydney Swans ruckman Mike Pyke will face a fitness test this week after rolling his ankle late in Sunday’s win over Carlton at Etihad Stadium.

Swans physiotherapist Matt Cameron confirmed that Pyke’s injury was only minor, but said the big man will need to get through the club’s final training session later this week.

“(Pyke) rolled his ankle later in the game but he was able to get back out there and he looks like he’s just injured the ligaments on the outside of his ankle,” Cameron told SwansTV.

“Usually within a week they are pretty much right, but this week is a shorter week so we’ll just see how things go.”

Midfielder Jude Bolton will spend a month on the sidelines after hyper-extending his knee in Sunday’s match.

Scans revealed yesterday that the 32-year-old had suffered partial tears to both his anterior-cruciate ligament and his posterior-cruciate ligament following a collision in the third quarter of Sunday’s clash.

Cameron said Bolton also suffered a degree of bone bruising as a result of the injury.

“The scans showed that he’s done some damage to his knee and when you hyper-extend your knee like that, you usually do some damage,” he said.

“Luckily, he hasn’t torn any of the ligaments completely.

“The two cruciates inside have had some partial injury to them, and also the back of his knee capsule, which are the softer tissues that have been hurt.

“(He) also has got a bit of bone bruising at the front from when the two bones come together.”

Cameron added that while the recovery time for such an injury was difficult to predict, he estimated Bolton will return in a month’s time.

“He’s already improved each day since and we’re hoping (the length of time out) will be something like a month,” he said.

“It is a little bit unpredictable when you have bone bruising as some of those things can take a bit longer, but we’ll be hoping for the best.”

In other injury news, Swans forward Sam Reid is set to return to the training track next week after a positive week of rehab.

Cameron said Reid, who partially tore the medial ligament in his right knee in the Swans’ round 18 clash with the Gold Coast Suns, showed plenty of improvement this week.

“His knee is improving each day and he started running this week,” he said.

“We are hopeful that he’ll be able to continue running and resume training next week.”

Meanwhile, Swans ruckman Mark Seaby is faced with another setback after re-injuring his calf in training last week.

“(Seaby) has been out with a calf injury and unfortunately last week he was very close to training and doing his last session before joining the group and he felt a bit of tightness again, so we’ve had to pull back again,” Cameron said.

“It might mean that he isn’t going to be running again until next week, which is a bit of bad news for him.”
