Broncos coach Kevin Walters has copped criticism for his decision to not substitute Reece Walsh off the field until very late in Saturday night’s 34-10 victory over the Wests Tigers.

The superstar fullback gave fans reasons for concern during various moments in the  second half, looking to be in some discomfort on the pitch.

Walsh struggled to his feet while making tackles, was seen vomiting after scoring his second try and was also seen grabbing at his calf and knee with what looked like a cramp.

Despite this, the Queensland No. 1 remained on the pitch until very late in the match.

Walters assured footy fans that Walsh was fine and had not suffered any serious injuries.

He (Walsh) had vomiting first and then he had the cramps,’ Walters said.

‘He had every injury known to man tonight, but he’s OK, he’ll be right for next week, so that’s a good thing.’

Adam Reynolds was also struggling towards the end of last night’s match too, coming off in the 77th minute with cramps.

Jock Madden will go for scans on his pectoral injury as star duo Selwyn Cobbo and Ezra Mam race the clock to be fit for the Broncos’ grudge clash with the Sydney Roosters.

Madden, playing five-eighth, left the field in the 61st minute of Saturday night’s 34-10 win over Wests Tigers in Campbelltown.

He will have scans on Monday to asses the scale of any damage.

Centre Cobbo (shoulder) and Brisbane’s regular No.6 Mam (finger) missed the Tigers clash.

The pair will train on Tuesday when their injuries will be assessed ahead of Friday night’s showdown with the Roosters at Suncorp Stadium.

The last time the Broncos played the Roosters – in Las Vegas for March’s high-profile season opener – Mam was called a ‘monkey’ by Tricolours prop Spencer Leniu, who was subsequently suspended for eight weeks for the racial slur.

The incident, reported by Mam to officials on the field and supported in writing by teammates after the match, sets up an explosive re-match.

Brisbane coach Kevin Walters said after Saturday’s Tigers victory that Mam and Madden were in doubt for the Roosters clash.

‘I wouldn’t think (Mam would play) … and Jock, possibly not,’ Walters said when asked about the the duo’s expected availability.

‘We’ll come up with something. I’m not sure. Jock is pretty sore and it’s a shorter turnaround, but we’re not going to put Ezra at risk this early in the season.

‘We could play anyone there and they will get the job done for us.’

If both are unavailable, Walters could slot the versatile Tristan Sailor into the No.6 role or shift Billy Walters – who has featured in the halves at NRL level previously – from No.9.
