"I'm definitely glad to be back," Ellis said. "It has been a strange start to the season and I have been desperate to get back playing again, but you have to be careful with hamstring injuries.
"I was pleased to get off the bench against Munster, though it would have been a lot nicer if we had won the game.
"It was a fierce battle, it was everything we had talked about, a big battle between two top teams. The weather conditions had an effect too but, credit to Munster, they kept plugging away and they got the result in the end."
Now it is looking forward rather than back as Tigers look to get their Heineken Cup campaign back on track with Sunday's trip to face Cardiff Blues at the Millennium Stadium.
"It is back to training and we are all looking forward to putting it right in the next game," Ellis said. "You have got to win your away games and that is what we hope to do."
