The forward was recently out of action with the problem and has admitted he noticed signs of the injury reoccurring in the defeat to Wolves on Good Friday.
“To be honest since I came off against Norwich, I’ve not touched the training ground,” said Blackstock.
“My hamstring has been very tight and even today it wasn’t ideal – I knew how important the game was so I gave myself every chance.”
Forest boss Dougie Freedman is in a difficult position because he’ll want to keep a presence and some experience up front ahead of the club’s final important games in the Premier League season.
Chuba Akpom has made his debut for the club, but it’s still a very big ask for him to patrol the frontline and lead the attack of the team.
That increases the importance of Blackstock, but it’s important the forward doesn’t take any risks and that the manager doesn’t use him this afternoon against Brentford unless he’s completely ready.
Hamstring problems are one of the most delicate to manage and if not treated in the right way, they can become long term problems.
A good example is the problem, which Chelsea striker Diego Costa has been carrying since before the Champions League final for Atletico Madrid last season.
Hopefully Blackstock wouldn’t have suffered any further setbacks following the match last week and hopefully he’ll make it through the game today without any further issues if he is used.
