Erinle is currently with Wasps but his contract expires at the end of the current campaign, while Blaze is at Premiership strugglers Worcester.
Tigers coach Pat Howard said: "Erinle is an excellent finisher and has the ability to break the line.
Tigers forwards coach Richard Cockerill said: "Richard is one of the best young English locks around at the moment."
The 6ft 3in, 17-stone Erinle made his Wasps debut in 2002 and scored 11 tries in 19 games during the 2004-05 season.
He went to the Churchill Cup with the England A squad last season and has previous international experience with England Sevens and Students.
Richard has the potential to be a very good player

The 27-year-old is currently working his way back to full fitness after a broken leg, an injury picked up during Leicester's win at Wasps in November.
His departure was described by Wasps as being "by mutual consent".
"It was a massive decision to leave Wasps but I just felt it was right to take on a fresh challenge," Erinle said.
Blaze made his Premiership debut in the 2004-5 season and has represented England at under-18, under-19 and under-21 level.
Cockerill added: "With Leo Cullen due to leave at the end of the season, we have been looking to strengthen that area of the squad.
"Richard played in the second row alongside Tom Croft with England Under-21s and he has the potential to be a very good player."
Meanwhile, Wasps have confirmed that fly-half Riki Flutey will join at the start of next season.
The 27-year-old, who has signed a two-year deal from London Irish, can also play at centre.
He has scored 272 points, including 15 tries, in his 36 Exiles appearances to date, having joined the club in October 2005.
