I changed from "the following three weeks" to "when used", because when you write "the following three weeks", readers want to know when he scored his next goal. Lets say, after a month, he scores his next goal, then readers want it to be like "... he scored his next goal after one month." And we dont want overdetail so "when used" is much better, as he is isnt playing every game or a starter. So please don't revert it. His next goal we mention should be a important goal for him or the team so "when used" is better.
