The Celtics made their first notable change to their roster 

by agreeing to sign Blake Griffin to a one-year 

guaranteed deal during training camp on Friday. 

The news comes after the Celtics lost a number 

of forwards and bigs to injuries last month.

Danilo Gallinari is expected to miss 

the season with a torn cruciate ligament, 

and Rob Williams is expected to recover from knee surgery in 2023. 

With Luke Cornette spraining his ankle this week, 

he will be out for the next two weeks.
